Hi alistu,
I think you did not understand my question. PLZ first understand then reply. I do not need 0001 combination,this “0001” combination work very well by this switch. i said that, when i put 00000000000000 and 1111111111111111 in the user define bit sequence generator then both the output ports of two switch display 50fW powered steady line, but for a switch, one port should display 1mW and other port should display 0W. And my question is why they act like this? What is wrong with this switch?
